Billy Crystal, Meg Ryan and director Rob Reiner reunited Thursday to celebrate "When Harry Met Sally's" 30th anniversary at the opening night of the TCM Classic film festival in Hollywood."It was thrilling when they said, 'We want to honor the film after all these years,' and to see the attention that it's getting and to see how people are reacting to seeing all of us together," Crystal told Associated Press on the red carpet. While Ryan posed on the red carpet in a sleek suit and platform boots, her beloved costar snuck up behind her to give her a hug, making us nostalgic for their on-screen duo in the 1989 rom-com. The actress noted her undeniable chemistry with Crystal, telling attendees at the event, "It맥스카지노�s the kind of music Billy and I knew how to play together," per People. Of course, the night could not go on without mention of the movie's classic deli scene: "I'll have what she's having," a curious bystander (played by Reiner's own mother) iconically says after the performance. Apparently, the bold moment was Ryan's idea. "Meg was the one who said, 맥스카지노�I맥스카지노�ll do it. I맥스카지노�ll actually do it,'맥스카지노� Reiner recalled, per Entertainment Weekly. 맥스카지노�The idea was we gotta have something that men don맥스카지노�t know about women because earlier, where they맥스카지노�re in the plane together and Billy talked about after sex, how a man feels and all that, and we were saying we need a counterpoint," Reiner continued. "And Meg said, 맥스카지노�I맥스카지노�ll do it, I맥스카지노�ll just actually act it out. We don맥스카지노�t have to talk about it. I맥스카지노�ll do it.맥스카지노� And I had the idea, 맥스카지노� in a restaurant!'"As for her character's daring gag, Ryan explained, "The comedy of Sally is so behavioral. It맥스카지노�s not so much talking, it맥스카지노�s doing, so it was very logical, it wasn맥스카지노�t hard to do."
